Japanese Waterstones: SIGMA Select II

SIGMA Select II The sharpening stone manufacturer SIGMA Power Corporation in Tokyo has designed these premium stones especially for tough-to-sharpen high alloy steels, like High Speed Steel, for instance. When using these stones, one can easily see it working, and they have a feel while sharpening remarkably like a natural water stone. In contrast with resin-magnesium or cement bound stones, these SIGMA Select-II stones have no binding material. The method used to bind the grit is much more like the process of making glass. As the stone is cooled, the viscosity is increased, hindering crystallization and the material emerges in an amorphous state. This process is expensive, but results in a stone that really eats its way through even the toughest steels.

Of course, the steel is not the only thing quickly ground away and sharpening quickly produces a thick slurry and the stone tends to get hollowed out more than others -- the price for speed! So the Select II stones must be flattened relatively often. On the bright side flattening is also a relatively quick process!
